Stability is an issue here. While the OS might get a code corruption in the
kernel by who-knows-what, this is less likely to happen in the on-board
memory (RAM/ROM) of the RAID controller.
If the system crashes for whatever reason, who knows what gets written back to
the disks. Most likely nothing, since the OS already died. Your RAID
controller will most likely still flush it's buffers back to disk and leave
everything as good as it gets.
just my 2c.
Best regards,
Chris
